Overview

Compatible with both 12V and 24V systems, 70A PWM solar charge controller features adjustable low voltage disconnect (LVD) and low voltage reconnect (LVR) settings, float voltage, and a boost charging function that activates when the battery voltage drops below 12V, boosting for 2 hours. The 70A controller provides comprehensive protection with battery overvoltage protection set at 16.5V, reverse connection protection, and load overcurrent protection that restarts every two minutes if necessary. Offers overvoltage, overload, reverse polarity, and short-circuit protection. Solar charge controller can be used in residential solar power systems, RVs, boats, and remote cabins, providing a stable power supply for lighting, appliances, and other electrical devices. It is also suitable for agricultural and industrial solar power installations.

Feature

FAQ

Q1. Why is my controller not powering on?

This issue can be due to a poor or loose battery connection, a battery voltage that is too low, or a blown internal fuse. Ensure all battery connections are secure, check the battery voltage and charge if necessary, and inspect and replace the internal fuse if needed.

Q2. Why is the load not working?

This can be due to the load terminals being off, the load exceeding the controller’s capacity, or the load short circuit protection being activated. Check if the load terminals are on, ensure the load does not exceed the controller’s capacity, and reset the controller if needed.
